/* Time converter generator gadget.  Selects from one of three
 * conversion algorithms: ones that take advantage when the
 * frequencies are an integer ratio (in either direction), or a full
 * precision conversion.  Clever use of extra arguments causes all the
 * selection logic to be optimized out, and the generated code even
 * reduces to 32 bit only if a ratio conversion is available and the
 * result is 32 bits.
 *
 * This isn't intended to be used directly, instead being wrapped
 * appropriately in a user-facing API.  The boolean arguments are:
 *
 *    const_hz  - The hz arguments are known to be compile-time
 *                constants (because otherwise the modulus test would
 *                have to be done at runtime)
 *    result32  - The result will be truncated to 32 bits on use
 *    round_up  - Return the ceiling of the resulting fraction
 *    round_off - Return the nearest value to the resulting fraction
 *                (pass both round_up/off as false to get "round_down")
